  • SiOC composite electrode material
    Patent number: 10611642
    Abstract: A SiOC composite material in microparticulate form, wherein the microparticles are formed, in whole or in part, of an amorphous SiOC matrix with Si ranging from 20 wt % to 60 wt %, O from 20 wt % to 40 wt % and C from 10 wt % to 50 wt %, based on the total weight of the SiOC matrix, wherein amorphous or crystallized silicon particles are embedded within the SiOC matrix and wherein the microparticles are of core/coating structure with a core formed of the amorphous SiOC matrix and coated with at least one amorphous carbon layer; and to a method for producing such SiOC composite material. It also relates to an electrode active material, an electrode and a battery, especially a lithium-ion battery, including the aforementioned SiOC composite material.
